Signal Too Low. Intermittent Fault

Signal too low. Intermittent fault

Checking the control module for open-circuits
Remove relay 2/116.
Check the driver circuit for the relay coil for an intermittent open-circuit as follows:
Measure the voltage between terminals #1 and #2 on the relay base. For further information about intermittent open-circuits, see Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Activate the relay driver, window up: Click on the VCT2000 symbol.

Hint: The voltage between terminals #1 and #2 should be battery voltage.

If the value deviates excessively, check the voltage between terminal #2 and the battery and between terminal #1 and ground. Both should equal battery voltage. Check for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Do not forget to check that the power supply to the control module is OK.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).

Yes - Attempt New Test

No - Fault Found
